留兰香茎叶粉对肉兔生长性能和屠宰性状的影响

摘要

在肉兔饲料里用5％、10％和15％留兰香茎叶粉替代相应苜蓿草粉探讨留兰香茎叶粉对肉兔生长性能和屠宰性状的影响.结果表明:与对照组相比,5％留兰香茎叶粉组和10％留兰香茎叶粉组平均日采食量、平均日增重有改善向好的趋势(P＞0.05),15％留兰香茎叶粉组平均日增重显著降低(P＜0.05),3个组全净膛重、半净膛重、全净膛率和半净膛率均有提高的趋势(P＞0.05).添加10％留兰香茎叶粉替代苜宿草粉效果较好.%The experiment was conducted to study the effects of 5% ,10% and 15% of spearmint leaf powder on production and slaughter performance of meat rabbits. The results showed that:Compared to the blank control group,the average daily feed intake and average daily weight gain in 5% group and 10% group increased slightly (P>0.05) ,while average daily weight gain in 15% group decreased significantly CP<0. 05).the semi-eviscerated weight.eviscerated weight,semi-eviscerated percentage and eviscerated percentage in the 3 experimental groups increased slightly(P>0. 05). The addition of 10% spearmint leaf powder instead of alfalfa grass powder was better.
